WASHER Filed Jan. 30, 1930 Patented Sept. 2,2, 1931 UNITED STATES RICHARD W. RIGLER, F PHILADELPHIA, PENNSYLVANIA *'arasninaA Application med January so; i930.l serial No. 424,661.

The invention has relation to washers for materials used in industrial processes, such as rubber, pulp, sand, etc., and has foran object certain improvements whereby greater economy of construction and operation will be obtained as will be explained.

The invention consists in the novel construction and combinations of parts as set forth in the appended claims.

In the accompanying drawings illustrating an embodiment of the invention, Figure l is a central longitudinal section on the line 1 1, Figure 2; and Figure 2 is a cross section on the line 2 2, Figure 1.

In these drawings, the numeral 1 designates a rotatable drum or tank for the Wash liquid, of elongated cylindrical form, having support and rotary bearings upon rollors 2, engaged by annular bands 3 of the tank, the latter being rotated by suitable means (not shown) engaging annular gear 4 of the tank.

' This tank is provided with spaced partitions 5 and 6 of annular form, of progressively increasing diameter of orifice or opening 7 and with an annular end wall 8, the oriice or opening 9 of which is also of progressively increasing diameter as related to the openings of said partitions, said annular end wall 8 having a bell mouth 10 for wash liquid discharge purposes into a trough 11.

lash liquid is introduced into the tank through pipe 12. It will be noted that the tank is divided into a plurality of compart-V ments (three as shown) 13, y111, and 15 by the annular partitions 5 and 6, andthat due to the progressively'increasing diameters of the openings of the partitions and the opening of the annular end wall 8 of the tank, the wash water introduced by the pipe 12 into the compartment 13 at one end of the tank is allowed to reach a certain level therein when it will overflow into the ad- `jacent or middle compartment` 14, wherein 7 it is allowed to reach 'a certainlower level,

when it will overiio'w into the compartment 15 at the other end ofthe tank, wherein it is allowed to reach a certain still lower level, when it will overflow into the drain ,terialidischarged fromfthe compartment of `the tankf at that,V endthereof. VAnyannular rplate-21 havingv perforations 21.',y isypiovided in compartment 15 at the end there-V i' trough 11. rhe reason for the successively vorY progressively vlower levels of the wash liquid in the' several tankcompartments is of coursedue to theprogressively increas-V ing diametersof the openings of the annular 'partitions 5 and v6 and of the end wall'8. The circumferential wall 4of the tankis provided in each of the three compartments with an' annular series of inwardly extending anges'l, forming pockets due; to'the inclination of thelanges as yseen in 00 end--vie'w,' said vflanges being also arranged spirally orinclinedv longitudinally, soa-s to successively raise material Vbeing treated vand allow it to drop back into the wash liquid, and to feed thel material being washed to- 5 ward the discharge end of the compartment or towards the scoop that elevates' and advances Athe material "as will' be explained. 'Suitably securedto thetank in each compartment thereof isV one or morek arcuate '70 scoops y17, terminating at vits inner end lslightly below the level of the center of keach compartment aslthe scoop arrives at the top ofthe tank in they rotation 'thereof thelower end portion'of they scoop lbeing extended laterally through the opening of the adjacent annular partition at 17', so that material picked up by each' scoop in its vrotation with theA tank is delivered :into the nextadjacent compartment andisfinal- "8 ly discharged `from thef end compartment wherein the wash liquidI hasl thehighest level.r` The scoopsl are perforatedto'drain the 'material ibeing washed for 'obvious- 85 `A feed :chu-tegor pipe 18` is provided dischargespoutor chute.19 to receive'ma- .90

Signed at Philadelphia, in the County of Sludge collected in the compartments of Philadelphia and State'of Pennsylvania.

the tank may be discharged through pipes or conduits communicating with openings Y 20V of the tank. Manhole openings may be provided at a. y

The operation is as follows 13 through pipe 12, and after `illing RICHARD W. RIGLER.

the partition 5,`the wash liquid overflowsv 'Y l into the compartment 14 to the level of they Y lesser breadth of the partition 6,"overfiow's into. thecompartment 15, and after filling the same to the `level ofthe still lesser breadth ofk the annular end wall 8 of the tank,4 overflows into the drain trough 11.

Material to be Washed is fed in through the pipe l18 Yinto the compartment 15, Where it Vis successively raised by the flangesland dropped back into the compartment. As the material accumulatesk in this compartment, it is picked up-by the scoop 17 thereof and Vwhen raised s to V,the Y.upper s portion .of thecOmpartment y-loy rotation of the .tank `slides kthrough the chute formed bythe innerend. portion of said scoop into the compartment lwhere it is` subjected to similar n treatment'in the l,Washliquidjwhich` in this compartment is less-.contaminated with the .impurities of the materiallbeing* washed. The material isl transferred from .the compartment.11to the Vcompartment 13 in 4the vsameway and is therein subjected to .the

-same treatment in the clean incoming` wash water.V The .thoroughly washed material is discharged .through discharge ,spout z19.

Due to the fewer parts andless obstructongreater economy in constructionand operation is secured.
